Interesting "thread".....
Just thinking about this and the issues with using the threaded coupler making a bump when making up longer sections of pipe.
For those who are suitably equipped with thread tapping equipment perhaps the bore of the pipes could be tapped to suit a section of threaded rod thus creating a flush joint

The pipes flex especially with longer lengths which can bow a glue up if you don't space the pipes from the wood a little and put the same number on the top. That way the pressure is balanced. Easiest is to put a few wood spacers on the bench so the pipes are 3 to 6mm below.

The joining of two pipes is with an external coupler or bushing. Here when you get pipe the truck length pipes have one end threaded and comes with a thread protector that is about the same thickness as the pipe. The bushings used for installations and take pressure are thicker than the protectors. Both work for the purposes of clamping as they only need to be hand tight but the protectors don't make as big a bump. The insides of the pipes are not threaded normally so trying to make internal couplers would involve non standard parts or having to adapt other kinds of threads to make it work.
